4/6/8/12-Way Automotive & Marine Blade Fuse Box — ATO/ATC • 12/24V (Max 32V) • Clear Cover • CE/RoHS
Build a clean, serviceable 12/24V DC distribution with this multi-way blade fuse box. Available in 4, 6, 8, or 12 circuits, each block uses standard ATO/ATC 6.3 mm blade fuses, side-entry 6.3 mm spade terminals, and a clear, vibration-resistant snap-fit cover for fast visual inspection. Rugged ABS + metal construction, CE/RoHS compliance, and IEC-aligned safety practices make it a solid choice for automotive, marine, RV, off-road, and upfitter installs.
Key Features & Benefits
- Up to 40 A per circuit: Supports common ATO/ATC fuse values (1–40 A) at up to 30–32 VDC systems.
- Service-friendly cover: Clear, snap-fit lid resists vibration and protects from splash and dust (not submersible).
- Fast wiring: 6.3 mm (¼") plated blade terminals on each circuit for quick crimp-on connections.
- Secure mounting: Two molded mounting holes sized for ~5 mm hardware; robust, compact enclosures.
- CE/RoHS • IEC safety standards: Materials and ratings aligned to common low-voltage vehicle/marine practices.
- Includes fuses: Each variant ships with an assortment for immediate use (see “Variant Specifications”).

What’s in the Box
- Blade fuse box (choose 4/6/8/12-way) with clear snap-fit cover
- Assorted ATO/ATC fuses (per variant above)
- Unit-integrated 6.3 mm blade terminals; mounting holes molded in base
Installation & Safety Notes
- Use correct wire gauge for the protected load (per-circuit ≤ 40 A) and crimp fully-insulated 6.3 mm female spades.
- Observe polarity and circuit labeling; keep total system voltage ≤ 32 VDC.
- Mount on a flat surface using the molded holes; avoid locations exposed to direct spray or submersion.
- Fuse each circuit to the smallest rated component on that branch (wire/device) — fuses protect wiring.
Frequently Asked Questions (FAQs)
1) Which blade fuses does this use?
Standard ATO/ATC automotive blade fuses (6.3 mm tabs), 1–40 A ratings depending on circuit needs.
2) What’s the max system voltage?
Designed for 12 V or 24 V DC systems (maximum 30–32 V DC, per variant notes).
3) Is the cover waterproof?
The clear lid is splash- and dust-resistant, not submersible. Mount away from direct spray and standing water.
4) What terminal size do I crimp?
Use 6.3 mm (¼") female spade crimp terminals for each circuit lead.
5) How much current per circuit?
Up to 40 A per fused branch when wired with proper gauge and protected with the correct fuse value.
6) Can I use this on a boat?
Yes—common on marine 12/24 V DC systems. Mount in a dry locker or cabin and use marine-grade wire/terminals.
7) Does it include a bus bar?
Each circuit terminates on 6.3 mm blades as specified. If a common feed/bus is required, incorporate an external distribution block per your design.
8) What are the mounting dimensions?
See the table above; for example, the 6-way is 115×53×42 mm with 5 mm holes spaced at ~107 mm centers.
9) Are fuses included?
Yes—each variant ships with an assorted fuse set (values listed in the variant table).
10) Operating temperature?
The 12-way variant specifies −20 °C to +150 °C. For all versions, avoid mounting near exhausts or heat sources; verify wiring insulation ratings.
